Projected global warming watermarks

The Watermarks Project is projecting estimated high water marks onto buildings in Bristol England if the Greenland ice cap melts.

One question: Since the Little Ice Age ended before the American Civil War, how much have sea levels risen in Bristol, England?

The phase between ad 1550 and 1850 when temperatures were generally lower in Europe and North America than they are at present, and glaciers advanced.

The 1841 sea level benchmark (centre) on the `Isle of the Dead', Tasmania. According to Antarctic explorer, Capt. Sir James Clark Ross, it marked mean sea level in 1841. Photo taken at low tide 20 Jan 2004.
Mark is 50 cm across; tidal range is less than a metre. ® John L. Daly.

Tasmania: 2004 sea levels similar to 1841 sea levels

These two photos are both derived from the photo on the main page. One has relatively light lines drawn over the mark to make clear where the mark is within the photo; the other is an enlargement of the central area of the original photo.
